This Viral Harry Potter Tattoo Is Actually a Terrible Idea

Not so magical.

Harry Potter*​ tattoos are a common ink choice, thanks the series’ large fanbase. Last month, J.K. Rowling even helped a fan get the tat of her dreams by providing the phrase 'expecto patronum' in her handwriting. Another Potter tattoo has captured the attention of the Internet, but this time because of its potential danger.

The tattoo has gone viral and has garnered over 1 million views on Imgur. It features several black ink footsteps tredding along a glow-in-the-dark quote. The quote, “I solemnly swear that I am up to no good” refers to Marauder’s Map. Normally disguised as a blank piece of parchment, the quote must be recited in order to reveal the actual map. On the tattoo, the quote can only be seen when a blacklight is placed over the skin.

As ​Mic​ points out, there is major harm that can occur from UV tattoos. They spoke to dermatologic surgeon, Dr. Joel Schlessinger, about what this kind of body art can do to your skin. Apart from causing allergic reactions in some people, Schlessinger told ​Mic​: “many inks that glow in the dark contain phosphorus, a dangerous element that can be incredibly toxic to humans depending on where it’s derived.”

Tattoo inks are not regulated by the FDA so there’s no telling what’s really being injected into your skin nor how much. ​Yikes​. This is one kind of magic we’re definitely not going to be toying with.
